> The "Node Cumulative Next Batch Process Time" Statistic
> If you have a look at the explain plan (attached). Following the definition,
> the JoinNode Node Cumulative Next Batch Process Time: 565471. So, it is the summation of AccessNode (Node Process Time: 892860) + DependentAccessNode (Node Process Time: 439) + JoinNode (Node Process Time: 2203120). The summation does not agree. 
>  The RelationalNode.collectNodeStats looks wrong (it's effectively only subtracting out the last node)
